Enhanced Discord member verification

Made using Typescript

This project was made with user friction in mind. I wanted it to be as minimal as possible. This means no logging into OAuth, or dealing with annoying captchas (I’m looking at you, recaptcha..)

Backend tech

Frontend tech

Now that we got some tech covered, let’s get into some more details. Keycard doubles as a full-stack application, with the API, Discord bot, and frontend all in one. This is possible using HTTP interactions, which make the infrastructure all in one place, and without a hassle.

When a user verifies themselves successfully, their Discord ID and hashed IP address are stored into a table, (see schema here). This is saved for the alt detection, which scans this table for the same hashed IP address. If there’s a match, then a log is sent to the configured Discord channel.
